Syntax

Delphi:

type TSLRealBuffer = class( TSLLinearMemoryBuffer, ISLRealBuffer, ISLData )

C++ Builder:

class TSLRealBuffer : public TSLLinearMemoryBuffer

Visual C++ (MFC):

class CTSLRealBuffer : public CTSLLinearMemoryBuffer

C# (.NET):

public ref class TSLRealBuffer : Mitov.SignalLab.LinearMemoryBuffer

Summary

Delphi Real data buffer.

Description

This is Real(double) Data wrapper buffer. Use this buffer to access and manipulate the Real(double) data from inside your Delphi code. .NET, C++ Builder and Visual C++ users should use the much more convenient and powerful TSLCRealBuffer class. Note Delphi only.
